Abstract
Preparation of hydroxy-terminated conjugated diene polymers, particularly polybutadienes, by capping of organodilithium- and organopolylithium- terminated conjugated diene polymers or polybutadienes with lower alkylene oxide or epoxide capping agents in the presence of certain potentiating agents or catalysts exemplified particularly by small proportions of N,N,N.sup.1, N.sup.1 -tetramethylenediamine (TMEDA).
